I CARL E. WARE, OF MANCHESTER, NEW HAMPSHIRE.

PITMAN SHELL-ROLLER.

Specification of Letters Patent.

Patented Nov. 23, 1920.

Application filed February 18, 1920. Serial No. 359,626.

Be it known that I, CARL E. WARE, a citizen of the United States, residing at Manchester, in the county of Hillsborough and State of New Hampshire, have invented'a new and useful Pitman Shell-Roller, of

which the following is a specification.

The object of my invention is to provide a device to replace and eliminate theobjectionable features of the present solid onepiece pitman roller used in warp or filling spinnin and twister frames which is objectiona le by reason of its tendency to accumulate particles of waste which cause the roller to bind and the friction thus produced commonly stops the roller.

I attain the object of my invention by the mechanism disclosed in the accompanying drawings in which Figure 1 is an end elevational view of the device in use; V

Fig. 2 is a longitudinal section of'my invention; I

Fig. 3 is an end elevational view of same;

Fig. 4 is an end elevational view from the opposite end; and

'Fig. .5 is a side elevation of the device i with shell 1 removed.

Like numerals designate like parts in each of the views.

Referring to the accompanying drawings, I provide a roll 4 having ends 6 of the same diameter as the body of the roller. These ends function as trunnions. Roll 4 is provided with an annularflange 5 and a suitable oil groove 7. Revolubly mounted on roll 4 I provide a novel cylindrical shell roll 1, having an annular recess 3, adapted to receive the annular flange 3 of roll 4.

In operation the shell roll 1 is revolved on the roll 4 the trunnions of which rest without rotating in the spinning frames. In consequence of this operation an accumulation of waste about the .trunnion ends 6 of roll 4 does not impede or stop the opere ation of the shell roll 1, thus saving wear upon roll and cam of the frame (illustrated' in Fig. 1), and providing a roll which does not have to be oiled except at long intervals. The device effects a great saving in the matter of time and production.

It is within the contemplation of my 'invention to apply the device to different sizes and styles of rolls for different makes of spinning and twister frames.

What I claim, is:

In a device of the class described; a roll having an annular flange spaced from one of its ends, ajshell roll of less length than the first mentioned roll and revolubly mounted thereon, the-1shell roll having an annular portion adaptedto abut against the flanged portion of the first mentioned roll, the first mentioned-roll having an oil groove formedtherein.

CARL E. WARE.
